In this paper the data of temperature,precipitation,mean relative humidity,mean wind speed,and the number of hours of sunlight Duolun County,and the linear trend estimates and five - year moving mean method were used to analyze the climate change trends for nearly 60 years ( 1953 - 2012) . The results show that the annual average temperature and average temperature showed an upward trend,the annual average temperature tendency rate was of 0. 39℃ /10a,winter warming had the greatest contribution to the year - on - year warming tendency rate was of 0. 57℃ /10a; Annual precipitation downward trend was at a rate of 7. 17mm/10a,annual precipitation had the largest contribution to the decreased summer precipitation; The mean relative humidity, wind speed and sunshine hours also showed a downward trend,the annual trend rate were: - 0. 82% /10a,- 0. 11( m/s) /10a,- 51. 95h /10a respectively; the largest contribution to the annual decline was respectively the winter,winter and spring; The trend of climate change was same in this county with the national,Xilin guolemeng and Hunshandake.
